On 15th October, 2016, the OSA student chapter at Zhejiang University organized an outdoor activity in Suzhou City, Jiangsu Province. This activity is aimed at leading our members of OSA student chapter to appreciate the beauty and culture of the ancient city.

Suzhou, a city with a long history on the shores of Lake Taihu, is well known for its beautiful bridges, pagodas, and meticulously designed gardens such as the famous Humble Administrator’s Garden. Walking on the street of ancient town, we can hear the beautiful Suzhou opera, a typical culture in China. Also, local flavors are very delicious and worth to eat.

On the first day of the traveling, we appreciated the Pan Men and Hanshan Temple. Firstly, we visited the Pan Men at the south-west of the ancient city. Pan Men, one of the eight gates of ancient Suzhou, was built at 514 B.C. to shield the city. In the presence of the old gate, we appreciated the work and intelligence of ancient people. And then, we got to the Hanshan Temple, a small but famous temple of China. In China, we all know the famous poem about the temple. With the tolling of the Buddhist Temple, the culture of the Buddhism can be appreciated.

After a good night, we went to the Lingering Garden at the second day. Liu Yuan, one of the four most famous gardens in China and occupying an area about 5.8 acres, is located outside of the Changmen Gate. It is well-known for the exquisite beauty of its magnificent halls and various size and shapes of stones. It can represent the Chinese ancient garden art. In 1997, the garden was recorded on the list of the world heritage by UNESCO. We listened to the tour guide and appreciated the magnificent of the typical garden.

Tired but happy, members of the OSA student chapter at Zhejiang University took part in the outside activity. Through this activity, we appreciated the ancient city and cultureof Suzhou and communication of the members is accelerated.

On Jan. 17th 2016, the OSA student chapter at Zhejiang University organized a communication activity with teachers and students in a public welfare organization named “Youth Family”, located in the Hangzhou City, to help kids left behind. Aiming at arousing their interest in study, we gave them an introduction to some basic optical knowledge. Members of our chapter arrived at the school at 1:30 p.m. And then, we prepared for the class for about half an hour. The class began at 2:00 p.m. and gathered about ten students and seven volunteers.

(Participants attended this activity and show interest in our topic)

In the whole afternoon, one lecture focused on the topic called Interesting Optics. The aim of this activity is to teach them something about simple optical phenomena and develop the interest in optics.

During the class, Jingye Chen, members of OSA student chapter at Zhejiang University, gave them a class about the topic mentioned above. Xiaoman Shen, the former chairman of OSA student chapter at Zhejiang University; Hao Wu, Jiang Li, Jing Jia, members of OSA, guided them to do some demonstrative experiment of optics using optical suitcase.

(Members of our chapter and volunteers done experiments with these kids)

Firstly, they show the suitcase to these kids and make them do these experiments by themselves. Then, with the help of our members and volunteers, kids saw the surprising phenomena. At last, our members tried to ask more questions to make these kids think about the causes and make all of the kids participate in it. Some of kids raised their hands actively and answered questions perfectly, in which students had been excited from the interesting phenomena of experiment. To our surprise, three of the students understood the regularity and theory of polarization in the class.

(Students answered teacher’s questions and kids explained their opinions in the platform)

Time flew, though kids were immersed in the interesting experiments have not seen before. We gave all of them experiment equipment of the optical suitcase as a keepsake after class. These kids who answered questions well received gifts prepared for them.

Through this activity, the kids had expanded their horizons, particularly about optics. They were highly encouraged to have experiment on their own, and were taught how to solve the problems they might meet in the future. Our members establish the contact with the organizers, so that we can help more students after this activity.

On Dec. 17th 2015, the OSA student chapter at Zhejiang University organized a communicating activity with teachers and students of Chaoshan Centre Primary School located in the suburb of Yuhang District, Hangzhou,China, aiming to warm them up in the winter and arouse their interest in science. At the same time, we gave them an introduction of some basic optical knowledge. Twenty of our members took part in it.

The class began at 9:30 a.m. There were about 75 students attending our activity.

（the class is in session）

From morning to the afternoon, three lectures were reported in the class focusing on two different topics. One of the topics was to teach them some optical phenomena and the other one focused on the psychological health, including teaching them to firm in spirit and try their best to work hard.

During the first class, Weixi Liu and Huifang Chen, members of our OSA student chapter, gave them a class about the first topic mentioned above. They explained some basic optical phenomena to them, such as pin-hole imaging and mirage. They tried to ask more questions to make all of the students participate in the class. Most of the students raised their hands and answered these questions perfectly. At last, Jiang Li, the vice president of OSA student chapter at Zhejiang University; Jingye Chen, Jing Jia and Jingguang Tong, officers of our chapter, guided them to do some demonstrative experiment of optics using optical suitcase, and the students were excited to learn a lot from the interesting phenomena. To our surprise, one of the students found the explanation of polarization experiment in the class. All of the students were immersed in the interesting experiment. We gave them pieces of polarizers as a keepsake after class.

As regards the second topic in this activity, members from Institute of Optical Inertia, the joint organizer of this activity, gave these students a psychological training lecture about dreams. When asked what dreams they have, these students spoke out their dreams confirmedly. One student stood up firstly, and said, “I want to study optics in the future.” What a surprise! We were so happy to hear this voice coming from a little boy. Finally, we told them an inspiring story of an Australian person, Nick Vujicic, to encourage them and build up their confidence in life and study.

Through the whole activity, the students had expanded their horizons, particularly in the optics science. They were highly encouraged to have a dream and work hard, and were taught methods to solve the problems and overcome the problems they might meet in the future. Our members established the contact with the students, so that the students could get help after this activity. We are looking forward to cooperating with the teachers and students next time.

The Traveling Lecture from OSA did broaden our horizon and advance us to higher research level. Our student chapter are looking forward to the next Traveling Lecture.

On July 8th 2015, the OSA student chapter at Zhejiang University organized a youth education activity, inviting some of the first-year students from Hangzhou Changhe High School (http://www.hzchgz.cn/). Most of the students came from poor families, who had less education resources. Our event aimed at providing access to interesting and basic optics knowledge, meanwhile inspiring them to explore in the field of optics. The event was also supported by SPIE and IEEE student chapter at Zhejiang University.

The event was divided into 2 parts. Lectures delivered by our members gave the students a first glance of optics. Then the students were engaged in the experiments to gain practical experience of optical research.

The lecture began at 12:00 a.m. in the conference room of our center. Senling Zhang, an OSA member, gave a brief introduction to the college of optical science and engineering, along with the major of optical engineering. Jun Yuan, the president of IEEE student chapter at Zhejiang University, gave a talk about the development of optics. Christian Huygens, Isaac Newton, James Clerk Maxwell and Albert Einstein were introduced with their fundamental theory and great contribution. Students obtained a rough picture of optics through these lectures and some basic knowledge they might use in the following experiments.

(Pictures of Senling Zhang and Jun Yuan giving lectures)

After lectures, students were divided into 10 groups, taking turns to join the different experiments. For each experiment, one member was in charge of explaining the principle, demonstrating the operation and instructing students to finish it by themselves. We had designed 9 basic experiments shown in the following table.

With the instruction of our members, students understood some basic optical theory through interesting and visualized experiments, which gave them a deep impression. Most of the students were so deeply attracted by different experiments that some students even did not want to leave after the gathering time.

Through this event, our chapter enhanced our friendship and long term cooperation relationship with Hangzhou Changhe High School. We shouldered our responsibility of youth education, spreading optics knowledge to more young students. Our members practiced their skills of presentation and communication with teenagers during this event.

In order to promote our chapter and attract more new members, we held a spring out. We chose LASER World of PHOTONICS CHINA in Shanghai as our destination to attract more freshmen major in optical engineering, since most of them are quite interesting in this exhibition. Meanwhile, we could visit the Shanghai Institute of Optics and Fine Mechanics Chinese Academy of Sciences (SIOM) and build our networking with the OSA student chapter at SIOM.

March 17, 2015, 11 members of the student chapter of the Optical Society of America (OSA) at Zhejiang University travelled to Shanghai to visit the LASER World of PHOTONICS CHINA and SIOM.

LASER World of PHOTONICS CHINA was held at the Shanghai New International Expo Center March 17-19. As Asia’s largest laser, optics, optoelectronics industry event, from basic research to industrial applications, LASER World of PHOTONICS CHINA lead the industrial trends, showcasing the full range of product, including lasers and photonics, optics and optical manufacturing, laser production and processing technologies, imaging, detection, and quality control. The exhibition attracted 715 exhibitors from 20 countries worldwide, showing their latest products, technologies and equipment.

As soon as the members stepped into the exhibition hall, they were attracted by all sorts of the exhibitions on display. In conventional optical exhibition, machine vision is undoubtedly a popular theme, which is usually used for production control and testing. The workshop on Machine Vision attracted a large number of participants. In laser and laser processing exhibition, all kinds of lasers, such as ultrafast lasers, high-power lasers, fiber lasers, semiconductor lasers, made the members appreciate the rapid development of laser industry. What the students saw gave them a more clear and comprehensive understanding of the practical applications of optoelectronic industry, which means a lot for their future research work.

(Members wandering at the Bund)

March 18, the members came to SIOM. Leading by the president of OSA student chapter at SIOM, we visited the Laboratory, which focuses on the Shenzhou Ⅱ project. They are now building the ninth laser road to enhance the power, which is important for fusion reaction. During the visit, some members communicated their ideas with the president of OSA chapter at SIOM in depth.

We came back to Hangzhou in the afternoon of March 18. This visit to Shanghai broadened our horizon of the optical technology and industry, also gave us a chance to get in touch with the research of SIOM.

Through this activity, we attracted 11 more new members to our chapter. Additionally, we met with the OSA student chapter at SIOM and exchange our experience in holding activities.

On Jan. 1st 2015, the OSA student chapter at Zhejiang University organized a communication activity with teachers and students in Changhe Senior High School (http://www.hzchgz.cn/) located in the outskirts of Hangzhou city, aiming at sharing the studying experience and life in high school and the university, meanwhile give them an introduction to the Optical Engineering and basic optical knowledge. Twenty of us arrived at the school at 2:30 p.m. We have a meeting first to assign our members to different classes.

The whole activity was divided into two parts. One was a psychological training program which was a new part this year, and the other was in-class lectures focusing on two different topics. One of the topic was to share the study experience and information of Optical Engineering and the other was concentrated on the psychological health, including teaching them to reduce the pressure during the study and examination, which is also a new topic this year.

During the psychological training activity, we had a training program to reduce the pressure during the preparation of coming College Entrance Examination, meanwhile increase their energy and concentration. Two students were picked up from every class and were divided into 4 groups. After an interactive game, everyone joined in and our members got familiar with each other immediately. Then, the students were encourage to give a talk about how to prepare for the College Entrance Examination at the subject which they were good at. At last, we give some demonstrative experiment of optics using optical suitcase, in which students had been excited from the interesting phenomena. Xiaoyan Wang, the former president of OSA student chapter at Zhejiang University, together with Borui Li, another member of OSA, distributed the equipments in the optical suitcase to the students. With the help of equipment, they explained the polarization, dispersion, diffraction of light to these high school students. Everyone was attracted by the interesting experiment and their vivid explanation. They were not willing to leave even when the time was up, so that the activity was extend for extra 20 minutes.

For the in-class lectures, our members were distributed to each class. We did not determine the content of the lecture, require members to concentrate on the topics we had mentioned above. As an example, Xiong Yang mainly introduced to these students about the colorful life in the university, in order to encourage the students to work hard and get enrolled by their dream universities. Shipeng Wang focused on his own experience during the study in high school. He suggested that students should not only engage themselves in the sea of examination papers, but also summarize and introspect themselves immediately after the exams. Keqi Ma and Penghao Liu introduced the optical knowledge and the Optical Engineering which we majored in to the students. There was a Q. & A. session after each lecture. Students from Changhe High School were so eager to ask all kinds of questions from the study in high schools and life in universities that some of our members even missed our time of gathering.

Through this activity for the Changhe Senior High School, the students had expanded their horizons, particularly in the Optical Engineering. They were highly encouraged to work hard for the coming University Entrance Examination, and were taught methods to solve the problems and overcome the problems they might met in the future. Our members also established the contact with the students, so that the students can get help after the activity was over. We are looking forward to cooperate with the members at Changhe Senior High School next time.

Every student in Changhe Senior High participated in the activity were asked to fill in a questionnaire to give a feedback to our activity. Almost every student was satisfied with our activity and was willing take part in again. More results of the questionnaire will be shown on our website.
